, JOSEPH ALLONAS., OFl MANSFIELD, OHIO, ASSIGNOR TO O. AULTMAN AND 4 H. H. TAYLOR, OF SAME PLACE.

Laim Putnam. 98,541, dated .rama/ry A'4, 1870 Lumen-paren The Schedule referred to in these Letten Patent and making part of the same.

:l'o all whom 'it 'may concern Be it known that I,.JosnPH-AL1.oNAs, of Manseld, in' the county oi' Richland, and State of Ohio, have invented certain new and useful Improvements inLnmberfDxiers, of which thelollowing is a'full, clear, and-exact description, reference being had to the accompanying drawings, making part of this speci f ieaton, in'whic`h- Figure 1 is a perspective view, and

Figure 2 isfa transversesectional view through the .linez'1,g. 1. l

y'.lhe invention relates to that class of 4driers, in

which steam is employed to finnish the heat used for evaporating the moisture contained in the lumber; and

It consists in, 'rst, a novel airangement of the 4drying-chamber within-al Vshell or cylindergin such A manner as to form an annular spa e between the two, in combination witlra systeni of team-pipes, so

connected with both the drying-chamber and the surrounding space 4or heating-chamber, as to` place the "steam perfectly under the control of the operator,thus

facilitating the process of drying lumber, and making it easy' for one lto `adapt his 'management-'to therequirement of the various kinds and condition of lumber which vhe is treating.

The invention further consists incertain improve-'- ments inthe method of closing the entrance to the Ydrying-chamber, as will be clearly understood 'from the following descriptionl of the construction and oper# ation of my ilnproved'apparaths;

In'the drawing- A representsY a s hell or cylinder, which, for convenience, I prefer to make of light hoilereiron.'

B is a smaller cylinder, constrcted' similarly to the larger one, A, and placed within it, in such manner as to leave an annular space, B', between the two.v 4B may be'` supported in proper position within A upon feet, it thought best. l

Cylinders A and B are united at'their ends by -lleads C, made preierablyfin such -form as tol serve,

not merely toconuect the .two cylinders, thereby coin` pleting the steam-chamber1B', but also'to serve as a head for cylinder B, 4care being taken that all joints between heads C and Vsaid cylinders, as well as all 4joints in the cylinders, shallv be made.steam-tight.l

In each head .C is a aperture,'of suitable size,

Ithrough which; to ii'itroduce the' lumber to be dried, ,this aperture'being closed, when required, by means f man-hole'plate D, held iuV place by boltd, passing uthrofugh bridge c" Should convenience make it necessaryfhead G may be'cnt out the full size of cylinder B, and the open end4v ne closed by a cap', properly secured,A

. when necessary.

E is a feedpppe, leading from the boiler to the outerl shell A.

E' is a waste-pipe,

leading from shell A. (See fig..1.)

F is a'feed-pipe, leading from the boiler to shell B.

closed tightly by means of man-hole plate D, said spun-yarn, or its equivalent,

plate being packed with Steam is then let into this cylinder, through stopcock f; cock j" being closed. The steam is kept 'ou the lumber such time as 'shall sufce to dissolve the sap, tar, and other' substances, with which the pores ofthe wood may be filled, and hohl thernin solution, so that they'shall be readily expelled during the next stage of the process.

The next step is to close cock f and open cock f', thus allowing the contents of cylinder B to ilow out,

y or, if it is preferred, I may,.bebre opening cockj', lill the annular chamber B'with cold water, thus creating a vacuum about the' lumber, and more eiectually fr eeing its pores of' sap.

Then draw ofi' the cold water through cock e', after which close said cock, and fill steam-chamber B through cock e, thereby bringing the temperature in.

` cylinder B up to such point as may befdesired, and

the lumber will be rapidly dried, the vapor produced by evaporation beingdriveu ontthrough cock f', which must be`left open for that purpose'.

' lt will be readily seen, from the above description, that the drying-chamber enclosed by cylinder B -and lthe steam-chamber B are entirely independent of, and may be disconnected from each other at will, and, in

fact, can he only connected'with .each other, through the medium of the boiler, except bv connecting feedpipes -E and-F.

' What is claimed as new. and smmht to be secured' ybv Letters Patent, is,-

In a lumber-drier, havingjndependent lumber and heating-chambers, the arrangement, substantially as described, of two independent sets of induction 'and eduction-pipes, one set connectingwith the. inner chamber, and the other set connecting with the outer chamber.
